Improved machine for making bullets



cited gieten @anni @Wina Letters Patent No. 93,613, dated August. 10,1869.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be .it known that I, JAMEs E. GRANNIss, ofthe city and State of New York, have invented, made,

and applied to use, a new and useful Improvement in Bullet-Machines; andI do hereby declare the following to he a full, clear, and exactdescription of the said invention, reference being had to the annexeddrawing, making part of this specification, wherein- Figure l is a sideelevation ofthe machine for making bullets, the upper of thecompressing-wheels and segments being in section.

Figure 2 is a front view of the same, with one of the Wheels in sectiontransversely of its axis.

Similar marks of reference denote the same parts.

This machine is for the purpose of compressing, into a globular form, asquare or cylindrical slug of lead, that is cut oli' from a bar .or rodof metal.

My invention relates to a series of grooved rollers, combined withconverging grooved segmental dies, the same being` so arranged that thecube or cylinder of lead is reduced, by successive stages, to-a globularform, witha smooth surface.

Ihisconstruction of machineallows for the use of roughened grooves, toact, in the iirst instance, in re-l ducing the angles, and giving aglobular form, thereafterto'be finished and smoothed inthe subsequentoperations.

In the drawingv a 'representsthe frames of the machine, sustaining `ktheshafts b cd, that are geared together, and driven by competent power.

Upon the projecting ends of the shatts b c d are the grooved rollers cfg, the upper 011e of which, e,`i s nfade with a semioircular groove inits periphery, that has a ronghened surface; the secondv roller, f, hasa similarly-'shaped grooved periphery, ibut' smoother? and thesemicircular groove in thev periphery of the roller g is to be smooth.

' The grooved segmental diesh k l are each formed with semicrculargrooves inV their inner faces, the groove in l being smooth, or nearlyso, and thatin h sufficiently roughened to act with the roller e.

'lhese dies h k I are attached by screws, 2 2and adjusted by screws, 33, so that the lower ends are nearer to the rollers than the upper ends,so that the grooves slightly converge, inorder to compress thev slugsgradually into a globular form.

` I provide clearing-points, projecting into the grooves of e andvf,respectively, that prevent balls that may adhere in the groove beingcarried over ,the second time, and cause them` to pass into the groovebelow.

The bar or strip of leadis supplied by means of rollersml n, that arepressed together by means of springs, so as to grip the metal, but notcompress it, and, if desired, several pairs of rollers maybe ,con-

`necte'd together, so as to insureth'e proper feed of the bar or strip.n

I employ a cam, o, connecting-rod p, and ratchetwheel, to partiallyrotate the rollers, and feed forward the bar through between thecutting-surfaces r s; and a stop, t, that is adjustable, determines thesize ofthe slug that is cut off.

The cutter l.r is L actuated by a lei'er, u, and rod, e,

that is operated by the cam fw.

The parts are so formed and placed that the feeding of the bar isbetween the strokes of the cutter r, and x is a hopper, .to guide thecubical, prisma'tic, or cylindrical slugs into the grooves of the rollere and die, to be operated upon .in the before-mentioned man' ner, andformed into a globular shape.

What I claim, and desire/to secure by Letters Patent is v he arrangementof the rollers, e, f, and g, and adjustable segmental grooved dies, h,k, and l, in the` manner specified, so as to reduce the slug bysuccessive stages into a. globular form, substantially as set forth.

In Witness whereof, I have hereunto set my signature, this 20th day ofApril, 1869r JAS. E. GRANNISS.
